What is the value for m, and how do you solve the equation showing work?

A mass m at the end of a spring vibrates with a frequency of 0.88 Hz. When an additional 680-g mass is added to m, the frequency is 0.60 Hz. What is the value for m, and how do you solve the equation showing work?What is the value for m, and how do you solve the equation showing work?
After a whole bunch of math my physics book says that


w^2 = k/m. Yours probably does too. So, what to do with it?





.88^2 = k/m


.60^2 = k/(m+680gm)





From the 1st one, k = (.88^2)*m. You can solve the 2nd for m from here.





Work:


W = F*d = -k*d^2What is the value for m, and how do you solve the equation showing work?
